Memory IC Overview

The Renesas Electronics Corporation 71321LA55PPGI is a high-speed static random access memory (SRAM) component featuring a 16 kbit storage capacity organized as 2K x 8. It operates with a 55 ns access time and supports parallel interface communication. The device functions within a supply voltage range of 4.5 V to 5.5 V, drawing a maximum power current of 140 mA. Designed for surface mount applications, it utilizes a TQFP-52 package. The component supports an operating temperature range from -40°C to +85°C and includes humidity sensitivity features.

Memory IC Feature Summary

Features true dual-ported memory cells allowing simultaneous access to the same memory location
Includes internal interrupt logic with two INT flags for port-to-port communications
Contains on-chip port arbitration logic and BUSY output flag for error-free operation
Supports automatic power down mode controlled by CE for low standby power

Memory IC Applications

Interprocessor communications in stand-alone systems
Master Dual-Port RAM configuration with SLAVE 71421 units
Systems requiring full-speed data bus expansion to 16 bits or more

Memory IC Procurement Notes

Verify RoHS compliance status and moisture sensitivity level before integration. Confirm package dimensions match PCB footprint requirements. Check for specific manufacturing date codes if long-term availability is critical. Ensure supply voltage limits align with system design constraints.

Memory IC Selection Notes

Select this model when simultaneous dual-port access and internal interrupt signaling are required. Suitable for designs needing master-slave expansion without discrete logic. Verify thermal performance within the specified industrial temperature range. Consider package type compatibility during layout planning.

Memory IC Part Context

Part of the 71321LA series, designed for high-speed asynchronous operations. Offers TTL-compatible single 5V power supply support. Provides battery backup capability with 2V data retention. Available in multiple package options including TQFP variants for flexible board integration.
